负阻振荡器 meaning in Chinese
negative resistance oscillator
negative-resistance oscillator
oscillator utilizing negative resistance
Examples
- First of all , single port negative impedance oscillator is analyzed in the thesis . a design method of gunn diode vco is introduced and an vco chip using gunn diode is fabricated . the substrate of the vco chip is gaas with dimension of 4 . 4mmx3 . 9mm
本文首先对单端口负阻振荡器进行了分析，给出了gunn二极管负阻振荡器的设计方法，设计出了一个变容管调谐平面微带gunn二极管vco芯片，该芯片以gaas为衬底，尺寸为4 . 4mm 3 . 9mm 。 - It also gives the motive of the ka - band vco and mixer , associated with the subject ' s requirement and the realistic conditions , according to which a proposal is confirmed that the gunn diode and the varactor are mounted in the same cavity to fulfill the vco and an antiparallel diode pair is used to fulfill the harmonic mixer . in chapter 2 , based on the basic theory of negative resistance oscillating , we analyses the gunn oscillator and it ’ s tuning character . chapter 3 introduces the theory of millimeter - wave harmonic mixer
以此为根据结合课题需要和实验室的实际条件,确定vco采用耿氏管腔体振荡器形式,变容管与耿氏管安装在同一个腔内以进一步减小体积,采用反向并联二极管实现谐波混频;第二章介绍负阻振荡器理论及其调谐原理;第三章介绍毫米波谐波混频器基本原理;第四章给出了振荡器及谐波混频器的设计过程,整个组件联调的结果;最后是结束语,分析了电路中存在的问题,指出了改进方向。
